9-2. Soldering Conditions
Products can be applied to reflow soldering.
(1) Flux,Solder
Flux
Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Solder
Use Sn-3.0Ag-0.5Cu solder

(2) Soldering conditions
•
Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited
to 150
℃
max. Also cooling into solvent after soldering should be in such a way that the temperature difference
is limited to 100
℃
max.
Insufficient pre-heating may cause cracks on the ferrite, resulting in the deterioration of product quality.
•
Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and / or resulting
in the deterioration of product quality.

Tip temperature: 350°C max.
•
Soldering time : 3 (+1, -0) seconds.
•
Times : 2times max.
Note: Do not directly touch the products with the tip of the soldering iron in order to prevent the crack
on the ferrite material due to the thermal shock.

9-5. Attention regarding P.C.B. bending
The following shall be considered when designing and laying out P.C.B.’s.
(1) P.C.B. shall be designed so that products are not subject to the mechanical stress for board warpage.

(2)Components location on P.C.B. separation.
It is effective to implement the following measures, to reduce stress in separating the board.
It is best to implement all of the following three measures; however, implement as many measures as possible
to reduce stress.
Contents of Measures
Stress Level
(1) Turn the mounting direction of the component parallel to the board separation surface.
(2) Add slits in the board separation part.
(3) Keep the mounting position of the component away from the board separation surface.

(3) Mounting Components Near Screw Holes
When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during
the tightening of the screw. Mount the component in a position as far away from the screw holes as possible.

9-6. Mounting density
Add special attention to radiating heat of products when mounting the inductor near the products with heating.
The excessive heat by other products may cause deterioration at joint of this product with substrate.
9-7. Operating Environment
Do not use this product under the following environmental conditions, on deterioration of the Insulation
Resistance of the Ferrite material and/or corrosion of Inner Electrode may result from the use.
(1) in the corrodible atmosphere such as acidic gases, alkaline gases, chlorine, sulfur gases, organic gases and etc
(the sea breeze, Cl

9-8. Resin coating
The impedance value may change and/or it may affect on the product’s performance due to high cure-stress of
resin to be used for coating / molding products. So please pay your careful attention when you select resin. In prior to
use, please make the reliability evaluation with the product mounted in your application set.
9-9.
Cleaning
Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken
solder joints. Before starting your production process, test your cleaning equipment / process to insure it does not
degrade this product.
9-10. Handling of a substrate
After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the
substrate when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to
the substrate.
Excessive mechanical stress may cause cracking in the product.
Bending
Twisting
9-11. Storage Conditions
(1) Storage period
Use the products within 6 months after delivered.
Solderability should be checked if this period is exceeded.
(2) Storage conditions
•

•
Don’t keep products in corrosive gases such as sulfur, chlorine gas or acid, or it may cause oxidization
of electrode, resulting in poor solderability.
•
Products should be stored on the palette for the prevention of the influence from humidity, dust and so on.
•
Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on.
